Pressure Sensor ASDXRRX005PGAA5(ASDX005D44R) For Gas flow Instrumentation

Product Overview:

The ASDX series is a kind of silicon pressure sensor, which provides I2C or SPI digital interfaces for reading pressure within the specified full - scale pressure range and temperature range. It is fully calibrated, and the temperature compensation is carried out for sensor offset, sensitivity, temperature effect and non - linearity by using the on - board Application Specific Integrated Circuit (ASIC). The calibrated output value of pressure is updated at about 1 kHz. The standard ASDX is calibrated in the temperature range of 0 °C to 85 °C (32 °F to 185 °F).

Features:

• It has a ratiometric 12 - bit analog output.
• With precision ASIC conditioning, it has good performance in the temperature range of 0 °C to 85 °C (32 °F to 185 °F).
• It supports three pressure measurement types: absolute, differential and gage.
• The pressure range is wide, and this model can measure 0 to 5 psi (0 to 3.52 m H2O).
• It can work with a single - power supply of 3.3 Vdc or 5.0 Vdc.
• The total error band is within ±2.0% of the full - scale range at most.
• It complies with RoHS standards.

Pressure Measurement Types:

• Absolute Type: It has an internal vacuum reference, and the output value is proportional to the absolute pressure.
• Differential Type: Pressure can be applied to either side of the sensing diaphragm.
• Gage Type: Referenced to atmospheric pressure, it provides an output proportional to the change of atmospheric pressure.

Application Scenarios:

• Flow calibrators.
• Ventilation and air - flow monitors.
• Gas flow instrumentation.
• Sleep apnea monitoring and therapy equipment.
• Barometry.
• Pneumatic controls.
• HVAC systems.
